Patented Apr. 1, 1930 UNITED STATE PATENT orrica WILHELMA. A. H. HELWIG,OF DETROIT MICHIGAN, ASSIGNOR OF ONE-THIRD TO SAM DICKMAN, OF DETROIT,IlEIGI-IIG-AN vENriLArIne roar Application filed July 26,

This invention relates to ports for ships, and the object thereof is toprovide an improved port which will admit air, but not water,therethrough.

More specifically, the present invention aims to provide an improvedport so constructed that the dashing of the waves against the port, orthe submersion of the port by the rolling of the shipwill assist inforcing air through the port into the ship.

Another object is to provide a port wherein p the movement of the latterout of and above the surface of the sea will permit draining of waterfrom the port into the sea so as to suck foul air through the port fromthe ship.

The invention consists in the novel form, combination and arrangement ofparts hereinafter more fully described, shown in the accompanyingdrawings, and claimed.

In the drawings: V

Figure 1 is a fragmentary side elevation of a ship provided with a portembodying the present invention, looking at the outer side of the port.

Figure 2 is a similar view looking at the inner side of the port.

Figure 3 is an enlarged section on line 3-3 of Figure 1.

Figured is a section on line 4.-4 of Figure 8'; and

Figure 5 is a top plan view of the glasscarrying frame of the port.Referring more in detail to the drawings, the hull of the ship isprovided with spaced walls 5 and 6 formed above the normal water linewith alined openings in which is fixed a port hole casing 7 havingoval-shaped openings 8 through the top thereof. Hinged to the casing 7is a frame 9 carrying three spaced glasses 10, 11 and 12 and providedwith oval openings 13 at the top adapted to register with the openings 8when the frame is closed. The glass 11 divides the frame 9 into twochambers which, directly, are non-communieating. As the glass 11 isimperforate and has a waterproof fitting in the frame 9, the water maynot find passage by the same into the ship. 7

Arranged vertically between the walls 5 and 6 above the port hole is aninverted U- 1929. Serial No. 381,292.

shaped pipe 1 1, having flattened ends 15 fitted tightly in the-openings8 of frame 7, and providing communication between the chambers in theframe 9 at opposite sides of the glass 11. The outer glass 12 has itslower portion cutaway at 16 and is formed with a central opening '17,while the inner glass 10 is cut away at the top and bottom as at 18 and19. The pipe 14: is of a length to lead well above the water line of theships hull.

In operation, water willenter through the opening 17 and cut out 16 andrise in the outer leg of pipe 14., thus forcing the fresh air ahead ofthe same through the inner leg of pipe 14 and from the inner chamber ofthe port through cut outs 18 and 19 into the ship. The fall of the waterin the outer leg of pipe 14: sucks foul air from the ship through thecut outs 18 and 19 and the outer chamber of the port into the-pipe 14,and when the water drains from the outer leg of pipe 1 1 and the outerchamber of the portthrough opening 17 and cut out 16 into the sea, thisfoul air is drawn entirely out of the ship. 7 Due to the length of thepipe 14, no water will rise to the top bendof said pipe and passage ofwater arrangement of the opening 17 and cutouts 16, 18 and-19 insuresproper admission of air ahead of the water, ready exit and entrance ofthe air and water at the glasses 10 and 12,and unobstructed visionthrough the port hole. Moreover, the pipe 14 does not interfere withopening and closing of the frame 9, while theconstruction is simple anddurable, efficient in use, and capable of ready installation.

Minor changes are contemplated within the spirit and scope of theinvention as claimed. What I claim as new is: V 1. In a ventilated portfor ships, a casing having a pair of top openings, an inverted U-shapedpipe vertically disposed above said casing and having its ends fitted insaid openings, a frame in the casing having top openings alined with therespective openings of the casing,and a glass in saidframe on a planebetweenthe openings thereof to prevent the passage of water directlythrough said frame.

2.. In a ventilated port for ships, a casing. having a pair of topopenings, an inverted U-shaped pipe vertically disposed above saidcasing and having its ends fitted in said openings, a frame in thecasinghaving top openings alined with the respective openings of thecasing, and a glass in said frame on a plane between theopenings thereofto prevent the passage ofwater directly through said frame, and furtherglasses in the frame spaced from the inner and outer sides ofthe'first-named glass and cut away for permitting flow of air past thesame into and out of said frame.

3. In a ventilated portfor ships, a casing having a'pair of topopenings, an inverted U- haped pipe vertically disposed above saidcasing and having its ends fitted in said openings, a frame in thecasing having top openings alined withth-e respective openings of thecasing,-and a glass in said frame on a plane between the openingsthereof to prevent, the passage of water directly through said frame,and further glasses in the frame spacedfrom the inner and outer sides ofthe first-named glass and cut away for permitting flow of air past thesame into and out of said frame, said frame being hinged to the casing,the second named glasses being cut away at the bottom thereof.

4. In a ventilated portfor ships, a casing having a pair of topopenings, aninverted U-shaped pipe vertically disposed above said casingand having its ends fitted in said openings,a frame in the casing havingtop openings alined withthe respective openings of the casing, and aglass in said frame on a plane between the openings thereof topreventthe passage of water directly through saidframe, and further glasses inthe frame spaced fromthe inner and outer sides of the first-named glassand cut away for permitting flow of air past the same into and out ofsaid frame, said frame being hinged to the casing, the second namedglasses being cut away at the bottom thereof, the outer glass furtherhaving a central opening, and the inner glass being further cut away atthe top.

5. A ship provided With a hullcomposed of spaced walls formed withalined port holes, a casing for said holes provided with top openings,an inverted U-shaped pipe arranged vertically between said Walls abovethe casing and extending well above the water line of the hull, the endsof said pipe being fitted in the openings of the casing, a frame mountedin the casing and having top openings registered with the top openingsof the easing, and a glass in the frame ona plane between its topopenings to prevent passage of water directly through said frame.

6. Aship provided with a hull composed of spaced walls formed withalined port holes, a casing for said holes provided with top openings,an inverted U-shaped wipe arranged vertically between said walls a ovethe easing and extending well above the water line of the hull, the endsof said pipe beingfitted in the openings of the casing, a frame mountedin the casing and having top openings registered with the top openingsof the casing, and a glass in the frame on a plane between its topopenings to prevent passage of water directly through said frame, andfurther glasses in the frame spaced from the inner and outer sides ofthe first-named glass and cut away for permitting flow of air past thesame into and out of said frame.

In testimony whereof I afiix my signature.
